The world’s population is increasing drastically. Lands and greeneries are transforming into highly-standing buildings and well-developed societies. This need of humans is increasing the demand for building materials and construction in our society. Nowadays, contractors get assistance from estimators to use construction estimating services. As a contractor or a construction company, you must know how to calculate labor costs in construction. This guide will help you explore how you can evaluate labor costs in construction. 

What is Labor Cost?

Construction companies hire workers and other personnel in a building project to complete the job perfectly. These workers may include excavators, electricians, masons, painters, and other construction workers. On hiring these experts, companies pay them for their jobs, and this expense is known as labor cost in construction. 

Why Labor Cost Estimation is Essential in Construction?

Labor Cost Estimation in construction is essential to calculate accurate overall budget estimates and generate high-quality bids. Ignoring labor costs during construction project evaluation is one of the major mistakes contractors make and faces significant problems during construction. And most of them cannot win bids due to missing entries and low-quality bids. Therefore, one must consider labor costs in construction project estimation to complete his project without hurdles. 

How to Calculate Labor Costs in Construction

In old times, people used traditional methods to calculate labor costs. It was a time-consuming method with more chances of human errors. Today, we have the option of digital estimation. Moreover, many contractors get assistance from subcontractors or calculators to evaluate construction labor costs. Both are unreliable methods. A construction company cannot get precise and accurate estimates using these methods. 

Average Construction Labor Rates

Types of Construction Labor	Mean Hourly Rates
Foundation and building exterior	$ 19.65
Utility systems	$ 20.98
Non-residential building	$ 21.48
Residential building	$ 18.68
Specialty contractors	$ 19.94

Method to Calculate Labor Cost

If you want to become an expert in labor cost estimation, you must follow the footprints of estimators. They follow the following methods to calculate construction labor costs. 

• Unit Pricing Method 

The unit pricing method benefits labor cost calculation, particularly in project design and bid estimations. In this method, estimators use the following formula to calculate labor cost:

Labor Hourly Rate x Time Required to Complete One Unit.

Let’s take an example! 

You have a project to construct a wall. How much labor cost will it take?

Labor hourly rate                                       = $40 per worker

Time Required to Complete One Unit       = 12 hours  

Labor cost                                                 = $40 x 12 hrs

Labor cost                                                 = $480

It is a direct labor cost. If you want a more precise figure, you can also consider the material expense of the construction project, overhead expenses, profit, supervision, and other necessary markups in your bid. 

From where will this data come? 

Suppose you do not know the unit pricing for individual types of labor; you can use a cost database to collect essential data. Cost databases contain updated pricing information collected from the worldwide construction industry. 

Calculate Unit Price

If you want to calculate the unit price, follow the below steps:

1. First, calculate labor costs using the formula mentioned above. 
2. Second, figure out all material costs individually.
3. Third, calculate the total direct cost by adding material cost to labor cost. 
4. Last, calculate the labor cost per square foot by dividing the total labor cost by the square footage. 

Follow up….

You can add this data to the price cost database and do the same for the rest of the construction expenses. 

• Square Foot Method

The square foot method has strategic benefits over the Unit Pricing Method. It is a profitable budget tool that can give accurate estimates for last-minute high-quality bid generation. Engineers and architects mostly require budget evaluations in the early stages since they refrain from reworks and alterations after valuable time investment. Therefore, contractors use the square foot method to align with them for budget pricing. 

The square foot method is the fastest way to calculate construction estimates, including labor costs. It uses historical data for the construction budget estimation.

• Rule of Two Method

In the construction industry, experienced contractors use the rule of two methods for calculating construction labor cost since it depends on the experience and expertise of the estimator. For instance, professionals know the exact percentage of labor expense in a construction project, such as 40-50%. 

If you know your labor cost, follow these steps:

1. First, multiply the labor cost by 2.
2. Second, add 10% of contingency expenses to the figure calculated in the first step. 

If you do not know your labor cost, follow these steps:

1. Use the cost database to identify your construction project labor cost. 
2. Next, find the average labor cost and use it for further calculations. 

The rule of the square method needs critical thinking and technical expertise. You must be able to efficiently deal with your calculations or estimates according to your project’s custom items, difficult working conditions, complexities, and field conditions. This expertise will enable you to calculate the most precise and accurate construction estimates, particularly labor costs. 

Factors You Must Cover During Labor Cost Estimation

When calculating construction project labor cost, consider the following elements to get the most accurate figure, essential for flawless construction activities. 

• Payroll fraud
• Paid time off
• Payroll taxes
• Recruiting and training costs
• Equipment such as vehicles and company phones
• Worker’s compensation and other forms of insurance

Step-by-Step Guide to Calculate Construction Labor Cost

1. Base Rate

Consider three construction activities to calculate labor costs! 

Lead                             = $40 per hour

Journeyman                = $25 per hour

Apprentice                   = $15 per hour

In this scenario, the base rate is $80 per hour. 

What is the base rate in labor cost calculation? 

It is a unit price that is considered for calculating the labor expense. The term gives a starting point to contractors and estimators so they can calculate precise and accurate labor estimates. 

2. Labor Burden

The labor burden is the expense other than workers’ hourly rates. It may include benefits, incentives, bonuses, and other facilities offered by the company. 

Consider the following values to calculate the labor burden of each worker!

1. Employees’ hourly wages,
2. The number of hours they are available to work per year,
3. Number of days they can off each year. 

Let’s suppose a $20 per hour to understand this concept!

1. A person can spend 2,080 hours each year. Similarly, he can be out of the working station for 15 days yearly. 
2. If the single shift is 8 hours, multiply the 15 days by 8. 
3. Next, subtract the value from 2,080 hours to get the number of hours your workers work yearly. 

Here is its mathematical representation: 

15×8= 120. 2,080-120= 1,960.

The elements you can consider as examples:

• Benefits= $2,000
• Insurance= $1,000
• Payroll taxes= $2,000
• Supplies and other expenses= $5,000

Add all the expenses, and you will get the figure $10,000, which will be your labor burden. 

3. Labor Rate

Once you have the base rate and labor burden, you can identify the labor rate. 

1. For this calculation, simply add the hourly rates of the laborers working on a single construction project. 
2. Whatever the value you get, multiply it by the labor burden and markup. 

Always round the figure for accurate estimation and easy understanding. 

4. Construction Labor Cost 

We have 3 construction activities for which we have three workers. The project will last 6 weeks, and each team will work for 8 hours daily. Per week, it will be 40 hours of working. 

Crew’s hourly rate X 3 (amount of workers) X 6 (number of weeks) X 40 (hours per week) = Labor cost of the project.

Once you have your construction project labor cost, consider materials and other expenses to calculate and submit high-quality bids. 

Take Advantage of Construction Estimation Software!

Manually completing all these calculations can be time-consuming and may lead to human errors. Today, you have digital software and tools for estimating construction projects of all sizes. If you are not good at manual labor cost calculation, you must consider these helpful tools for getting precise and accurate data. 

Benefits of Labor Cost Estimation Software

• Less time consumption.
• Mobile app to monitor and manage labor.
• Money-saving tools
• Order tracking becomes easy 
• Optimized productivity

Cost estimation is a crucial aspect of project planning and management. It involves predicting the financial resources required to complete a project successfully. Various factors such as labor, materials, and equipment are essential to consider when estimating the cost of a project. Inaccurate cost estimation can lead to budget overruns, project delays, and failure to deliver results as per expectations. Therefore, it is mandatory to use appropriate methods of cost estimation to confirm the success of a project. In this blog, we will discuss some of the most commonly used cost estimation methods. 

List of Cost estimation methods:

1. Top-Down Method

The top-down method is a widely used cost estimation technique that involves estimating the overall cost of a project based on historical data and industry standards. In this method, we first estimate the total cost of the project, and then allocate it to individual phases based on their importance and requirements. In the construction industry, estimators mostly use this method during the initial stages of project planning. 

It provides a quick estimate of the total project cost, but it may not be accurate for complex projects or those with a high degree of uncertainty. The top-down method is useful in situations where there is limited time and resources available for cost estimation, and it is one of the most beneficial cost estimation methods for setting budget and timelines. 

2. Bottom-up Method

The bottom-up method is another popular cost estimation method that involves estimating the cost of individual tasks or activities and then adding them to determine the total project cost. In this method, project managers break down the project into smaller, manageable components and estimate the cost of each component based on a detailed analysis of labor, materials, and equipment requirements. 

It is a more accurate method than the top-down method and estimators use is for complex projects. It allows project monitors to locate and mitigate cost risks at the task level and provides transparent visibility into the project cost structure. However, it requires more time and resources than the top-down method and may not be suitable for projects with limited information.

3. Analogous Estimation Method

The analogous estimation method is one of the famous cost estimation methods that relies on historical data from similar projects to estimate the cost of a new project. In this method, project managers use their experience and knowledge to analyze similar projects and use their cost data for estimating the cost of the new project. This method is applicable when an estimator has a little project data, lack of time or resources for estimation. 

Unlike the Bottom-up method, it is a less-time consuming cost estimation method. It provides a quick estimate of the project cost, but it may not be accurate if the new project is different from the projects used as a basis for estimation. The analogous estimation method is useful in situations where there is a need to estimate the cost of a project quickly and where historical data is available for reference.

4. Parametric Estimation Method

The parametric estimation method is a cost estimation technique that uses statistical data and mathematical models to estimate the cost of a project based on specific parameters. It is one of those cost estimation methods in which project managers use historical data from previous projects to develop a cost model. Estimators utilize the cost model to estimate the cost of the new project based on the values structure, size, complexity etc. 

This method is profitable for projects with a high similarity to previous projects and where the parameters are well-defined. It provides a more accurate estimate of project cost than analogous or top-down methods and allows for a more detailed analysis of the cost structure. However, it requires a significant amount of historical data and statistical analysis, which may not be available for all projects.

5. Three-point Estimation Method

One of the most useful cost estimation methods is the three-point estimation method. It is a cost estimation technique that focuses on the uncertainty associated with project costs. The consideration is achieved by estimating three values for each activity in the project: the optimistic, most likely, and pessimistic estimates. 

The method requires detailed data for accurate estimation. The optimistic estimate is applicable in best-case scenarios, while the pessimistic estimate is useful for the worst-case scenarios. The most likely estimate is the cost that is most likely to occur based on experience and available data.

Conclusion

Simply put, here are several project cost estimation methods, each with its own advantages and limitations. Some are quick but not accurate and some are only for projects with restricted data. Ultimately, project managers must carefully consider the characteristics of the project and choose the most appropriate estimation method or combination of methods to ensure the ideal and gapless completion of the project.If you want more information related estimation, you can contact Bidding Estimating anytime.

Roofing is one of the essential components to consider in the construction of a house or any building. It’s a whole separate task in the construction phase and requires a complex costing structure. 

Doing wrong calculations can be a costly result for your pocket. You don’t need to hire labour for the roofing estimate. If you’re on a budget, here’s a DIY roof installation cost per square foot guide.

How much does roof installation cost per square foot?

Here’s a rough graph based on the average pricing and figures for the citizens of the USA:

Item	Cost Range
Roofing material (e.g. shingles)	$1,500 – $10,000
Labor	$3,000 – $8,000
Roof decking	$500 – $2,000
Roof vents	$300 – $600
Flashing and sealant	$500 – $1,500
Gutters and downspouts	$1,000 – $3,000
Total Cost	$6,800 – $25,100

However, that was just an estimated vague figure. The real cost of your roof always depends on various factors. It includes the size of your house, the number of floors, the type of material you want to use, and the inflation in your state. Here’s an in-depth guide on it:

Labour Involved In The Project

The labour influences the cost of the project to a large extent. Roofing must require professional and expert labour. Non-professional and newbie labourers can never perform a good roofing for your building. 

Of course, the more expensive labour you choose, the more money you’ll have to spend on the labour. The number of labour force depends on what type of roof you’re designing. The more complex and effort consuming roofing becomes, the more time and effort it’ll require, and the more money the labour will increase roof installation cost per square foot.

Type Of The Materials You Choose

The type of material you choose also influences the roof installation cost per square foot. The reason behind this is the quality of the material. The more good quality materials you choose, the better quality housing you would get. Good quality materials can last for longer and reduce the maintenance cost of the roof. However, they require a higher one-time cost investment. This investment influences your roofing cost to a positive figure. 

The Thickness Of The Roof

Well, this topic varies on the requirements of your building. The more thick roof you want to create, the more expensive your roofing will become. The thicker roof requires more TNT iron bars, more concrete mixture, and more labour work. Of course, that doesn’t come free of cost. 

That’s why it’s essential to build an ideal thickness of the roof. You can contact your BIM designer or architect regarding that case. The ideal thickness is important. The more thick the roofing will be, the more weight-bearing capacity it’ll have, making it ideal for a multi-story building.

Size Of Home And Location

The bigger your home is, the more expensive it will be for you to have a new roof installed on it. If you live in an area where there is a lot of snowfall during winter months then you might want to consider installing a metal roof instead of wood shakes or tile roofs because they won’t get as dirty from snow accumulations as wood shakes and tiles would.

Type Of Roofs

Metal roofs are usually more expensive than tile roofs because they require special care during installation and require longer drying times before they’re ready to be installed again on the TNT bars.

Tile roofs are also more expensive than asphalt shingle roofs because they need to be sealed once they’ve been installed to prevent leaks. The sealing process is not a cheap solution and you may need to spend about an extra 400$ on the sealing process. The additional sealing can increase your overall roof installation cost per square foot.

How To Reduce The Cost Of A New Roof?

Many people, especially budget people baulk at the cost of replacing their roofs, which can be as much as $15,000 or more for a new roof with shingles and a flashing system.

Here are some effective ways to reduce new roof costs:

Look At The Cost Of Replacement Materials

The price of materials will vary depending on the type of roof you choose. Some materials are more expensive than others due to their high quality and durability which offers lower maintenance. For example, asphalt shingles are less expensive than metal panels but still provide excellent protection against weather damage and sun exposure.

Additional Layer Of Shingles

You can add layers of shingles or tiles over the existing roof to help protect your home from damage and provide additional insulation value. This strategy saves you money in the long run. Because it extends the life of your roof and paints for several years. It may charge you extra in the short term, but in the long run, it’s a cost-effective solution.

The better idea is to go with the standard materials and designs recommended by the manufacturer or your contractor. The standard material is usually cheap in pricing and good for budget consumers. However, if you have a lot of experience with different types of roofs, you may want to consider using a different material or design.

How much does it cost to build a roof house?

The average cost to build a roof house is $15,000 to $25,000 depending on what materials you use and the size of your home.

Does the availability of space matter?

If you have large areas available for your project then it will be less expensive than if you do not have enough space for it.

Does weather influence the roof cost?

If your area has harsh weather conditions then you should expect a higher price for your roof house since these can increase costs significantly due to damage caused by heavy rains or snowfall
